A comparative study on fretting wear-resistant properties of ion-plated TiN and magnetron-sputtered MoS{sub}2 coatings

摘要

This paper studied the fretting properties and mechanism of TiN and MoS{sub}2 coatings on 1045 steel. The results showed that the fretting-resistant property of ion-plated TiN coating is obviously better than that of magnetron-sputtered MoS{sub}2coating on SRV fretting tests. Under the given test parameters (normal load 10 N, slip amplitude 100μm and frequency 10 Hz), the fretting wear mechanism of TiN coating is particle detachment through the propagation and fracture of fine microcracks onsurface, and the fretting wear mechanism of MoS{sub}2 coating showed its damage process by degradation and abrasion of materials.
